The effects of drought and disturbance on the growth and developmental instability of loblolly pine (Pinus taeda L.)

► Disturbed areas at Ft. Benning were used for military training. ► Disturbance enhanced growth of branches, needles, and growth rings of loblolly pine. ► Drought reduced growth of branches and needles and eliminated the stimulatory effect of disturbance. ► Disturbance had no effect on tree-ring complexity or developmental instability.
